Topic suggestions: While you have touched on many topics in your DIY videos, here are some items you might want to cover more in depth. Structural fillets vs sandable fillets, i.e., colloidal silica (and commercial varieties) vs microballoons vs commercial fillers; laminating resin vs finishing resin and working time; finishing or waxed gelcoat vs gelcoat sprayed when moulding pieces; PVA vs mould release wax; polyester over epoxy and vise versa; using thickened epoxy (or polyester) resin to waterproof through holes, mounting holes and screw holes; how large a patch should be over a holed hull. Your opinion on these topics I would greatly welcome.

[@FishBumpTV]

My dad was a boat builder our boats were called Grand Pass, I grew up in it. Love the videos I’m giving myself a refresher corse. My dad passed away in 21 so I don’t have him around to ask questions. I’m repairing the extension deck on his 76 Apollo he left me. I’m going to use Coosa instead of wood. Thanks for doing these videos they helped me remember the process. I miss my dad a lot his fiberglass knowledge was amazing. Keep up the great work.

[@stevehorswell2371]

Thanks for the various demonstrations and examples you've provided. I would enjoy seeing you build a wood/epoxy boat. I've built several wood/epoxy boats and have found that choosing the proper hardener for the ambient temperature greatly impacts the working time of the epoxy mix. Fast, medium, and slow hardeners are generally available for each brand of epoxy. I tend to use medium hardener if the ambient temperature is under 70°F and slow hardener if the ambient temperature is over 75°F. I rarely use fast hardener. Most epoxy manufacturers provide a temperature cure table showing working time using different hardeners at numerous temperatures. And, as your demo shows, large batches will "go off" more quickly than small batches. Thanks again.

[@FishBumpTV]

Thanks for your suggestions! We are always looking for interesting projects, a small wooden skiff seems like a natural fit. And yes, you are correct on the different hardeners for epoxy, we just went with fast to get maximum effect on the exothermic reaction! Thanks for watching

[@WereAllThatBored]

The standard is 77 degrees. Every 10 degrees above or below will half or double the working time advertised on the spec sheet. For small projects you can build a heat box with an incandescent lightbulb to speed up the cure time. Large parts like boats you definitely need to pay attention to the temperature or work in a controlled environment.

[@FishBumpTV]

[@MexicoPescadoro]

You're the man, man. You obviously HAVE to build us a small inshore boat for sure lol. Put me on that watch list for sure. I had to use some epoxy about a year ago and I made a little too much peanut butter with some fumed silica. As it sat in those little Total Boat mixing cups it started exo reacting hard and started smoking and was really hot to the touch on the outside of the plastic cup. It was gnarly. LOL I let it burn out and harden and then knocked it out of the cup the next day. Exo thermic reactions are no joke. But I wouldn't say dangerous. Definitely do NOT want to be breathing that stuff in though...

[@FishBumpTV]

Thank you much! Yep, I hope to keep the boat projects rolling out for you guys. Exotherm will kinda freak you out the first time you see it. Always best to be safe with this stuff for sure!

[@liamsigurdsson1698]

Loving all these videos. Made the decision to try and use polyester for a large deck repair because of your videos! Crazy how much cheaper it is

[@FishBumpTV]

Thanks you very much! Glad you are enjoying the videos!

[@winningwithoutracing7811]

Where are you buying your resin? I find most polyester is priced alarmingly close to what Raka prices their epoxy at. I actually said so much to Mike over there and he was sorta shocked at how expensive ortho polyester had gotten. Is so much that I'll often use Vinylester because I actually feel like I'm getting more for my money.

[@caj122892]

Good info for the beginners. Once we kicked about 10-20 gallons of old gel in a drum. It didn’t catch fire but it sure smoked a lot. Resin would not typically cause a fire alone but always want to be safe. I’ve shot temps on masses of resin/gel over 500°F. One note: west system and others epoxy manufacturers do not recommend thinning epoxy but obviously it can be done in a pinch for odd scenarios. I work with west daily and haven’t found a need to thin though.

[@caj122892]

Another tip to thinning epoxy: heat is the best solution to reduce viscosity because it doesn’t negatively effect the cured properties like thinning with solvents. Put the epoxy in a heated room prior to laminating or use a heat gun if it’s cold and you need to reduce viscosity. Laminating with 105 below about 60° sucks if the resin is cold too haha.

[@FishBumpTV]

Thanks! Yes run away exotherm can get your full attention, that's for sure. I know thinning can be a hot topic. I don't do it very often, but sometimes the material needs a little help in certain applications. We will probably touch on that topic some more in the future. I do appreciate you watching and commenting!

[@garycouch7708]

A temperature gun would have given interesting info. Love your channel.

[@FishBumpTV]

I have watched a few fiberglass videos. But all of them had the feel of someone just now experimenting with fiberglass but trying to pretend to be an expert. It's nice, and inspires confidence, to see someone who truly has a lifetime of experience, showing that it's not that hard.... If you just do a few things that aren't necessarily obvious.

[@FishBumpTV]

Thanks so much for your comment! Glad the videos are finding the right people and are helpful.

[@zodnanref]

There is a poliester resin here in my supplier in Brazil that are not pre-accelerated, which means we need to add Cobalt to it, and if you mix Cobalt with MKP, that results in a powerful reaction of fire like really fast!!

[@FishBumpTV]

Yes, that can be very dangerous! We do not deal with that kind of material in our shop, but I have heard of it. Thanks for watching from Brazil 🇧🇷

[@scottcraven9763]

I just found your videos and am enjoying all of them that I’ve seen. Very informative the way you talk through everything you’re doing. Lots of time I can’t just give my full attention and watch what your doing but I do listen and I am gaining so much knowledge because of your dialogue. You have been saying something about building a skiff but I was wondering if building a paddle board could show us the same thing. Maybe could possibly come up with a kit for someone like me that has no experience. Anyway. Great content and keep it up. Scott

[@FishBumpTV]

Fantastic, thanks for watching and listening! I appreciate your suggestions for content! Who knows, maybe we could do something like a paddle board, although a lot of the skiff build techniques would be simular and would cross over to a paddle board build.

Great suggestion! We don't see many boats with carpeting on the floors in our area, but I know it is very popular in fresh water boats. Carpeting can be glued down on a floor or deck after it has been fiberglassed and allowed to fully cure with no problems. I will try to touch on this topic in a future video for you.

Hey Captain Joe. Love your channel. I am beginning the process of restoring my late Dad’s 1991 Kenner 21’. I am in the process of putting a new transom. I am wondering if you know what type of wood they used in their stringers. The tops of some stringers can be dug out but about 2” down is some wood that can’t be dug out. I am guessing that wood is still good. The good wood seems very light surrounded by ¼ “ woven roven. Even if some of the wood is not good, the fiberglass around it is very strong. Should I replace them since the fiberglass is what is giving structure? Thanks for the videos!!

[@FishBumpTV]

I have always liked the Kenners. I had a 03 23ft model for several years. It was a great boat. Mine had some type of 3/4 marine plywood. Yours probably has the same type. I heard it was called excel 10, but I am not positive about that. It is hard to say if you should replace the whole stringer. Especially if the damage is very localized. You may be able to just repair or replace the affected area. I will try to make a video about this kind of problem. Hope that helps. Thanks for Watching!

[@RaginCajun71]

Thanks for taking the time to respond. Look forward to future videos.

[@poepflater]

Nearly had a problem this past week, I finally did some epoxy with RTU hardener the afternoon and that evening temps fall to 5 degrees.... the work was tacky and not curing for 2 days before I smartened up and put it out in the sun for 2 days, turning it so the heat got everywhere... finally, it dried!

[@papataffy]

Just found your channel and I am going to go through the video. I will be 60 next year and I decided to build a sailing boat, most likely some J. Welsford design. Never did anything like this, I will probably build some canoe first to gain some experience. I was inclined to use rather epoxy but some advantages of polyester resin found on this channel made me think. So let's see, I will dive into your channel now.

[@FishBumpTV]

Glad you are enjoying the videos and welcome to the channel! I think building a small boat first is a great idea for someone who is new to this kind of work, I am sure you will learn a lot! Vinyl Ester resins, like the one we show in our resin selection video is something that you might want to seriously consider as well. It has the strength, bonding, and waterproofing ability of epoxy, but the easier workability of polyester. Vinyl Ester has become one of my favorite resins to work with because of these qualities. I hope this helps and I wish you the best with you boat projects!

[@conoroshaughnessy2948]

Thank you so much for taking the time to walk through all of the details of this stuff across all your videos, I've been enjoying watching them as of late. I've done a decent number of surfboard repairs and I'm pleasantly surprised that some of the "tricks" I landed on after some heartache are some of the things you've pointed out. I've lately been going down the route of getting into marine canvas and upholstery as a career switch, and was wondering what your thoughts on the following are. Every boat I seem to come across for upholstery work has at least one area where there is visible wear and tear around hinges, grommets, and the like. I'm considering expanding beyond upholstery to address some of these minor issues and offer repair services, but am wondering if you see this as not worth the risk/reward as it would be something done on sight without any type of shop just in the boat yards. Specifically, where there are screw holes that have worked themselves out via corrosion, do you have any low impact suggestions on fixes for this? I see you're a fan of the NAPA Pro Strand, but wondering if thats sufficient or some type of lamination would be the professional grade for this type of repair. I know enough to be dangerous and tear things up, but also know enough to be weary of getting myself in over my head. Thanks again and keep up the great work!

[@conoroshaughnessy2948]

Also, as a video suggestion, something that might be fringe but I would personally enjoy would be how to create a mold for a hull. There's a type of surf craft called a "Greenough Spoon" thats historically been shaped from a blank. It's a very wasteful process since a vast majority of the foam blank is removed in the process, and one that could be done in a similar manner to making a hull in my opinion. I've heard of a semi recent run by Jeff Hull on the west coast creating a mold to make these and that it was successful. Not sure if it would appeal too much to your target audience if you were to make this type of thing specifically, but any small form boat mold would certainly cover all techniques necessary for something like this. Anyways, appreciate you reading this far, thanks again.

[@FishBumpTV]

Glad you are enjoying the videos, and finding them helpful! Some gelcoat and screw hole repair seems like a good addition to your business. 3M makes a high strength vinyl Ester filler that is very good, but expensive. You might want to consider trying some tests and experiments on some non critical parts, and just see how it turns out for you. Hope this helps and thanks for watching!

[@FishBumpTV]

Thanks for the suggestion! I plan on building a hard top mold for our 29 very soon. The basic process would the same as a small hull. I think you guys would enjoy seeing the process.

Is it better to use epoxy or poly to put the stringers and the transom in, then use poly on the fiberglass.

[@FishBumpTV]

Either one can be used, and there are pros and cons for both. Epoxy cost more, but bonds well to almost everything. Polyester is less expensive and I think can be easier to work with in some cases, but doesn't bond as well as Epoxy. Just remember it is generally not a good idea to put Polyester over epoxy. Hope this helps, thanks for watching!

Hey Joe I have a few questions whenever you have time. Thanks for the video! Q:1 After mixing up epoxy & catalyst in a measuring container ( like the ones you use) then pouring it into a paint tray is it best practice to immediately clean the measuring container if I want to reuse it? I know they’re cheap but my concern is that every time I mix a batch of epoxy I will need to use another new measuring cup. Q:2 I just realized I need to search your video log because you might have this covered already. But I’ll at least ask. When the end of the day comes and I’m ready to stop working, what’s the best practice for clean up? Can tools be wiped down/cleaned with alcohol ( when working with epoxy)? What should I do with used roller naps? Thank you again for the video! I wouldn't mind seeing a boat build either👍🏻

[@FishBumpTV]

Glad you are enjoying the videos. I keep a five gallon bucket with about a gallon of acetone and a lid on it in my shop for general cleanup. Alcohol and plain vinegar will also cut epoxy resins. I will try to do a video on cleanup for you guys soon. Hope this helps and thanks for watching!

I thoroughly enjoy your hands on demonstrations. Please keep up the awesome content. Can you advise what the shelf life of unopened polyester resin and caralyst is. I purchased some about two years ago and I'm wondering if it will still be usable. Thanks Stuart.

[@FishBumpTV]

Thank you! Will do! They say 3 to 4 months for the resin. Catalyst is longer.

[@stuartlane7107]

Thanks, Captain Joe. Have an awesome day.

Segment on prepping through bolting underwater line on a cored hull. Im installing a swim platform and want to through bolt the braces. Im thinking 3" diameter of solid glass and/or thicken epoxy?

[@FishBumpTV]

Thanks for the suggestion, that's not something we do very often, but I will try to touch on that!

Building a plywood epoxy skiff would be really informative to watch

[@FishBumpTV]

Thanks for the suggestion! we are seriously considering a skiff build, so stay tuned!

[@paulradford4100]

I was actually surprised by this video and the lack of smoke/flame.. Though i prefer to mix right, i have over catalysed on the odd occasion when wanting to get a job done quickly. I have to admit the tins i used would get almost untouchable with over mix. I also remember when learning to fibreglass being shown a safety video, where in a tin, over catalysed mix would give a puff of smoke, smoke quite readily and then ignite - all done with a timer. Too long ago to remember exactness though, but enough to always be cautious of over catalysing.

[@FishBumpTV]

Yes, it was an interesting experiment! I thinks we will try it again with some different conditions next time. It is always best to be safe with this stuff though! Thanks for watching and commenting

[@alternativebuilder]

I’m wondering how many layers of cloth you can wet out at the same time with polyester or vinylester. 2 or more, 4?

[@FishBumpTV]

2 or 3 layers in most cases, depending on the temperature and thickness of the fiberglass clothe and the catalyst rate. The hotter it is with a thicker fabric, the less fiberglass you would put on. Hope this helps and thanks for watching!

[@bcboncs]

Thatd be awesome if you could consider the epoxy boat build. I know you prefer vinylester but I am leaning toward epoxy for weatherproofing and uv protection. Can you comment on the different resins as they relate to full blown weather exposure including snow/ice and UV exposure? Thank you Joe, you're a great demonstrator and hands on teacher. Keep it up subscribed!

[@TLCBB]

question could a mould be made from a plastic sheet and if so what is the best way to get the fiberglass off the plastic mould

[@FishBumpTV]

I am not sure if that could work or not. Fiberglass does not stick very well at all to plastic, so that part is good. I try to show methods that I know will work, and are standard practice in the industry on our videos so you know that your project will turn out good. Anything outside of that and you might want to just do some experiments and see what you get. I hope this helps and thanks for watching!

@@FishBumpTV thank you so much for the reply

Don’t forget to use vinegar to clean up mixed epoxy resin only. I initially didn’t believe that vinegar would dilute epoxy resin, but the old Mexican trick really works wonders for clean up, runs, etc. Give it a try……amazing!

Great tip! Thanks so much for watching and commenting!

You are referring to wet mixed epoxy not dried epoxy correct?

Hey Cap'n joe! I was just scrolling back through the channel and came across this video and was just wondering if you ever have a problem with heat during the cure process? In my situation we have problems with the resin getting too hot and turning opeke or even a white color and was just wondering if you had any advice on how to prevent this from happening. Keep up the great work! I cant wait to see you build the hard top for the 29!

[@FishBumpTV]

Sounds like too much material being applied at one time, or to fast of an activator or too much catalyst being added. Try applying less material at one time or back down on the catalyst. I hope this helps and thanks for watching!

I left a voice message regarding a mini boat build the day before this video came out. I have a mold and would love to have you as a consultant to help me build a few, and you can use the build for KZbin content... a win-win, plus I would still pay for your services. I see you mentioned a miniature boat build, and I would love to have your input on my particular build. My fiance and I did a stitch and glue boat a few years back and that is where we got the inspiration for the miniature boat and coincidently led us to your channel. As always, great videos, and hope to hear back from you. ~Cody PS. Great camera work Logan!!

[@FishBumpTV]

Thank you very much, sounds like a interesting project! I will be in touch.

HI. I have a kayak built about ten years ago. I would like to make some changes but I don't know what resin was used. How to understand if it is made of resin with styrene or epoxy? Thank you

[@FishBumpTV]

It is hard to say for sure.A quality kayak could possibly be made out of epoxy resin. If you are in doubt and need to make repairs, I would probably use epoxy resin. Epoxy will bond to epoxy, vinyl ester, and polyester resin, but poly and vinyl don't bond well to epoxy. Just remember that gelcoat is polyester based, and isnt recommended over epoxy. I hope this helps, and thanks for watching!

[@Fabio-hb4vt]

Grazie!

I am repairing a badly damage very old 14 foot fiberglass sailboat. The centerboard box must have been replaced because it was made out of 1/2-in plywood and was almost completely rotted. I have made a new one out of marine plywood with 3 layers of epoxy saturated fiberglass cloth on it. It was held in place by one fore/aft stringer and lots of foam insulation. I am planning in attaching the new centerboard box to a 2/6 stringer [on each side. My question is what do I use to adhere the new epoxy centerboard box to the polyester fiberglass hull? I can use epoxy to attach the box to the stringer, but what the stringer to the hull. I understand that polyester to epoxy does not work too good.

[@FishBumpTV]

If I understand correctly, epoxy should work in that application. Epoxy will bond to epoxy and polyester. I don't recommend putting polyester over epoxy. Hope this helps. Thanks for watching!

Hi, I have a Honda Jazz. I want to manufacture a 24-tooth plastic gear for the side mirror myself. There are many chemical options available, but which liquid chemical should I use? I want to avoid the gear breaking while rotating, and I don’t want it to be affected by heat or cold. Please give me some advice, your fan is asking for your help.

[@33Templeton]

Hey, I’m really enjoying your content! This might be a bit much for a comment section but I could use some clarification. I am preparing to pop some osmosis blisters on our 1979 sailboat. I was told that I could fill the voids with either polyester resin or epoxy. I was planning on using epoxy but I didn’t realize epoxy did not work with CSM or Biaxial until seeing this video. Did I understand that correctly? How do you build out a cavity using epoxy if you can’t layer glass mat?

[@FishBumpTV]

Glad you are enjoying the videos. 1708 and 1808 biaxial fiberglass work great with epoxy, vinyl Ester and polyester resins. Csm or mat works best with polyester and vinyl ester resins. Csm can be used in some limited applications with epoxy, but I don't usually recommended it. Epoxy resin does not melt the fiberglass binders that hold csm together, causing it to remain stiff when you are trying to shape it. Epoxy or vinyl Ester resins are usually recommended for below the waterline applications, but it is not recommended to apply gelcoat over epoxy resins. I hope this helps, and best of luck with your project!
